如何预编译gulp-handlebars助手？ [英] How to precompile gulp-handlebars helpers?

问题描述

我使用gulp-handlebars将我的模板预编译为JS，但我无法使自定义的handlebars helpers也进行预编译。有谁知道是否有任何支持/预编译自定义帮助器方法的方法？

I am precompiling my templates into JS using gulp-handlebars but I am having trouble getting custom handlebars helpers to also precompile. Does anyone know if there is any support/way to precompile custom helper methods?

推荐答案

我注意到gulp-handlebars可以使用特定的句柄库，基本上覆盖了它的默认值。所以，通过创建我自己的模块并注册一些帮助器，并将它提供给句柄调用，事情就在本地工作。

I noticed that gulp-handlebars can use a specific handlebars library, essentially overriding its default. So, by just creating my own module and registering some helpers, and feeding that into the handlebars call, things are working locally.

// helpers.js
var handlebars  = require('handlebars');

handlebars.registerHelper('upper', function(str){
   return str.toUpperCase();
});

module.exports = handlebars;

然后在gulpfile中（如下所示）：

And then in the gulpfile (something like this):

var handlebars = require('./src/js/helpers.js');

gulp.task('handlebars', function(){
  gulp.src('src/html/*.html')
      .pipe(gulp_handlebars({handlebars: handlebars})) // override library here
});
